Subject:      character string parsing

Hi Folks,

I have a simple character string parsing problem that I am too
simple to solve.  I have a character variable called context
whose values consist of a string of numbers, sometimes followed by some
letters, and then sometimes followed a single number. I need to
some code that will identify those cases where the right most
character is a number and then output all the numbers and
characters to left.  So for example, 746AD1 would become 746AD;
752B2 would become 752B; 752 would be left unchanged.  Ive
appended a listing of typical context values.

Thanks for any help.

Best, Fraser
